Dynamic text in Flash 7 player

1

Hi
My dynamically loaded text works fine if I publish to flash 6. When I publish to Flash 7 it won’t show! I did find another thread on this and their problem ended up being syntax. I’ve checked over and over and can’t find a problem. Could someone have a look and let me know if they see anything that might be causing the grief? Here’s the code:

stop();
booksLoadVars = new LoadVars();
booksLoadVars.load("bookTitle.txt");

function showMission(){
	_root.attachMovie("mission","mission_mc",this.getNextHighestDepth(),{_x:375, _y:299});
	_root.createTextField("mission_txt",101,220,40,330,500);
	mission_txt.html=true;
	mission_txt.multiline=true;
	mission_txt.wordWrap=true;
	mission_txt.embedFonts=false;
	mission_txt.variable="missionContent";
	mission_txt.htmlText=booksLoadVars.missionContent;
	
myTextFormat = new TextFormat();
	myTextFormat.font = "Arial";
	myTextFormat.size = 11;
	myTextFormat.color=0x000000;
	mission_txt.setTextFormat(myTextFormat);
	}

mission_btn.onRelease=function(){
	showMission()
	}

PS. When I set embedFonts to true it won’t work in either flash 6 or 7.

Thanks for having a look!
